In 1882 the U.S. Senate ordered the Secretary of the Interior to submit a list of pensioners on the roll which he did. That list was subsequently published in five volumes. There are pensioners from the War of 1812 and all other wars up to 1883 but mostly they are Civil War soldiers, their widows or minor children who received a pension. The books were printed by the federal government and available free from Google Books. Illinois is in Vol. 3. You can also search it at Ancestry, not free.

The record contains the certificate number of the pension (which you will need if you want to get the pension record), the name of the pensioner, the reason the person got a pension, the Post Office of residence, the monthly pension and the date of original award. Note that some columns are blank. Note also that some amounts seem highly unlikely as a monthly amount and could be typo in the original book.
